proportion coordination, the copy or moulding, autoclaved curing processes such as made of a new type of inorganic building materials.Because of its high strength, light weight, and has a good performance can be processed and incombustible, so widely used in Marine bulkhead,

ceiling, and construction of nonbearing wall, there is a requirement for fire prevention and other places.Silicon plasterboard is building gypsum as

main raw materials made of a material.It is a kind of light weight, high strength, thickness thin, easy processing and sound insulation better

building materials, thermal insulation and fire prevention performance is one of the current focus on development of new light plate.

Plasterboard has been widely used in homes, offices, shops, hotels and industrial buildings and other structures within the partition wall,

The invention relates to an architectural adhesive, which is characterized in that the composition of the building glue comprises 28-50wt% sodium silicate water solution, 34-53wt% quartz sand and 8-35wt% magnesium silicate.Adhesive for a building, it is the following: the weight ratio of 4 to 6, PVA cellulose 6 - 12, 1 - 2, copolymer admixture from 0.01 to 0.05, according to the proportion of polyvinyl alcohol with hot water first fully dissolved, then adding cellulose, copolymer, admixture and stir evenly. The glue can be combined with Portland cement or construction gypsum to cement all kinds of light plates. This product is non-toxic and tasteless, harmless to the human body, is a wide range of uses, superior technical performance of environmentally friendly building adhesive.

The two are thermal insulation materials. Calcium silicate board strength, cheap, but the use of temperature is not high, the highest 1000 degrees.

Q:What is the main role of fly ash added in concrete products?

The workability of fresh concrete can be improved by adding fly ashThe workability of fresh concrete is affected by the volume, water cement ratio, gradation, shape and porosity of the aggregate. The fly ash is used for fresh concrete is the obvious benefits of increasing the slurry volume, slurry filled with aggregate between pores, inclusions and lubrication of aggregate particles, so that the concrete mixture has better cohesiveness and plasticity. The aggregate particles of fly ash can reduce the interfacial friction between the paste and aggregate, and improve the workability of the concrete mixture at the contact point of the aggregate.

Q:What are the exterior walls of the building besides the benzene board and the extruded board?

Foam heat insulation material mainly includes two categories, polymer foam type insulation material and foam asbestos insulation material. Polymer foam thermal insulation material has the advantages of small absorption rate, stable heat preservation effect, low thermal conductivity, no dust flying in construction, easy construction, etc., and it is in the period of popularization and application.

Q:What's the use of low carbon steel insulated nail hooks for power plants?

The current power plant thermal insulation is mainly carried out by use of various types of insulation materials, thermal insulation materials commonly used include calcium silicate products, pipes, rock and aluminum silicate fiber products, due to their different properties are applicable to different environments. The equipment with temperature at 300-600 DEG C often adopts aluminium silicate products and calcium silicate products to compound heat preservation. While the temperature is less than 300 degrees, the mineral wool products are usually used for thermal insulation.

Q:What are the raw materials of cement products? What's the function?

Water is necessary for the production of cement products, the role of water is to cement hydration. Generally, the water cement ratio of concrete is 0.40~0.65. If the water is too large, it will leave a hole in the concrete, which will affect the strength, density and durability of the concrete and even cause water leakage.

Q:What are the production methods of calcium silicate board material?

The two reaction method (also called combined method) is the most complete and easy to obtain process of high temperature, light weight and high strength calcium silicate products and calcium silicate boards, but its disadvantages are long process, high energy consumption and large investment.

Q:What are the main use of lime?

A rigid inorganic cementitious material consisting mainly of calcium oxide. Lime is made from limestone, dolomite, chalk and shell with high content of calcium carbonate and calcined at 900~1100 DEG C. Lime is one of the earliest cementitious materials used in human life. Lime is widely used in civil engineering and can be used in medicine in our country.

Q:What are the three major effects of fly ash in concrete?

Fly ash "micro aggregate effect" in the fly ash particle size is very small beads and debris in cement can be the equivalent of unhydrated cement grains, tiny beads equivalent to nano material and lively, can significantly improve and enhance the structural strength of concrete and improve the homogeneity of products, and compactness.

Q:What's the use of white portland cement?

White portland cement as the raw meal with the proper components till the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material. When grinding cement, allow limestone not to exceed 5% of the cement weight. White cement is mostly ornamental, and its manufacturing process is much better than ordinary cement. The gap is mainly used to hook white tiles, is generally not used in the wall, the reason is not high strength. It is available in the building materials market or decoration materials shop.
